R3 multi buttons with different AF settings

[PUHY]

Can you assign multiple buttons with different auto focus settings. For example back button is set for eye detection and shutter button is set for spot focus? I’ve tried this but still bounces.

Hi PUHY,

You can map different types of focus modes to different buttons. Information on customizing the button function mapping is on pages 973-984. Those pages list what functions can be mapped to each button. When you are customizing a button to start AF select that function and then press the INFO button. That will bring up the advanced customization features and it will allow you to set the specific type of auto focus you want the button to use.

If you need a copy of the manual it is available HERE. Once you are on the web page click on the Manuals button and the one to reference is named EOS R3 Advanced User Guide.

My question is slightly different.  I wish to use front button focus ,, usually set at small focus point.  I’d like to have a button assigned a larger focus point ,, ex the AF-ON button.  When I do that and activate ficus using the rear button, when I return to using the shutter button for my selected focus point and exposure , the focus point has bounced back to what was the selected point via the AF-ON button.   This hybrid set up can be accomplished on Nikon , but I can’t seem to achieve it on my R3 or R5.    I’ve reviewed the advanced guide.  Any advice ?
